CENTRIFUGAL DRIER.

Specification of Letters Patent.

Patented May 18, 1909.

T 0 all whom it may concern:

Be it known that I, OSCAR KEEFER, a citizen of the United St ates, and.a resident of the ciently York, have in. 1 its interior to run to itslower edge and then city, county, and State of New vented a new anduseful Improvement in Centrifugal Driers, of which the following is aspecification.

The object of my invention is to provide a machine of this class whichis adapted to receive hat bodies or bats and to dry the same by rapidlyrotating them in the drier about a horizontal axis, and also to providea suitable hood which will deflect the water thrown from the machine,and cause the same to be thrown into a well provided with a drain,whereby the water or other liquid thrown out by the centrifugal actionof the machine will be prevented from spreading beyond the limits of themachine and will be collected within the compass of the machine anddrained off. These objects are accomplished by my invention, oneembodiment of which is described below.

For a more particular description of my invention, reference is to behad to the accompanying drawings forming a part hereof, in which:

Figure 1 is a perspective view of my improved machine. Fig. 2 is a sideelevation of the same, a portion of the hood being elevated. Fig. 3 isan enlarged section of a portion of the drum, taken on the line 33 ofFig. 1. Fig. 4 is taken at right angles to Fig. 3. Fig. 5 is a crosssection of my improved machine. Fig. 6 is an end elevation of the hoodand the means for supporting the same.

Throughout the various views of the drawings, similar referencecharacters designate similar parts.

My improved drier 1, rests on a base 2 which is surrounded by aninclined well 3 which is adapted to receive the water which drains froma hood 4. surrounding the u per portion of the drier, the well 3 havinga diain 3 leading to any desired place. The hood 4 is supported bystandards 5 secured to the base by screws or in any other suitablemanner, and to the upper ends of these standards is secured the fixedsection 6 of the hood 4. The movable section 7 is identical with thefixed section 6 except that it is hinged there be raised as shown inpermit the operator to Figs. 1 and 2 so as to This hood 4 is shapedattend. to the drier.

"a high velocity,

substantially as shown, in the preferred embodiment of my invention, andextends suffifar to cause all water thrown against drip into the well 3from whence it is drained. The centrifugal drier 1 is supported bystandards 8 secured. to the base 2 in any suitable manner, as by boltsor screws 9, and each standard 8 preferably consists of two converginglegs united by a crossing at their lower ends and forming bearings 10 attheir upper ends. Each of the bearings 10 is provided with the usualbrasses 11, in which is journaled a shaft 12 in the conventional manher. One end of the shaft 12 extends through the hood 4 and is providedwith suitable pulleys 13, fixed thereto, by means of which it may berotated and on the outer sides of the bearings 10, this shaft 12 isprovided with collars 14 fixed thereto, which revents any end play ofthe shaft. This sha t 12 also carries a drum 15 formed with heads 16,fixed on the shaft 12, and united near their peripheries by means oftie-bolts 17 fixed by nuts 18 on each side of the disks 16. These disksmay be readily removed from the shaft 12 by with drawing the keys 19 bywhich they are held and also by removing the tie-bolts 17. The heads 16and the bolts 17 are preferably made of some metal which will notcorrode or else covered with a non-corrosive coating. The bolts 17arranged as shown, do not extend the entire circumference of the disks16 but leave a suitable gap, as shown, having a door 20 which is hingedto one of the bolts 17 and provided with a perforated lug 21 on theopposite side which is adapted to be held by a thumb screw 22, as shown.This construction ermits the drum 15 to be opened or closed at thevolition of the operator.

From the foregoing the operation of my improved drier will be readilyunderstood. Assuming the parts to be as shown in Fig. 1 the bats orother articles to be dried are inserted and the door is then closed asindicated in Fig. 2. The hood is then closed by having its part 7lowered and the drum 15 is then rotated by any suitable means, notshown, at so that all liquid is thrown to the interior of the hood 4 anddrains from its lower edge as described above. In a few minutes, aftercentrifugal force has removed all moisture from bats power is thrownoff,

the part 7 of the hood is raised, the door 20 is opened and the dry batsremoved and wet ones inserted when the operation is repeatedas'b'efore'. at 1/ While I have shown and described one em bodiment ofmyinvention, it is obvious that it is not to be considered as restrictedthereto, but is broad enough to cover all structures that com'e' within'the scope of-the claims.
